Try's trap

	import scala.util.Try

	// isn't the following line supposed not to compile ?
	val foo: Try[Unit] = Try{1+1}.map{x => Try{x/0}}
	// foo: scala.util.Try[Unit] = Success(())

	val foo: Try[Unit] = Try{1+1}.flatMap{x => Try{x/0}}
	// scala.util.Try[Unit] = Failure(java.lang.ArithmeticException: / by zero)
